Guzman, who was 17 at the time Eddie Leal was gunned down, used photos of an East Coast Internet model in the profile in attempts to lure young men, according to the Riverside County District Attorney’s Office.

His motive, prosecutors say, was simply to kill for a thrill.

On May 30, 2011, Leal, 23, a professional bantamweight boxer, went to meet Rebecca Santhiago, the sultry single he had been Facebook messaging with, at a San Jacinto park, according to prosecutors.

But first, Santhiago had asked Leal to pick her up a Four Loko drink, according to the Press-Enterprise in Riverside. She advised Leal to pick up her brother, who would guide him to a liquor store, the newspaper reported.
